Inhibit Function:
The converter is disabled when the INHIBIT pin is
shorted to the INHIBIT RETURN with an impedance less
than or equal to 1K ohm, and that the converter be
enabled when the impedance between the INHIBIT pin
and INHIBIT RETURN is greater than or equal to 500K
ohms.

Remote Sense:
A remote sense feature maintains the desired output
voltage regulation at the load. It corrects the voltage drop
along the conductors between converter’s output and the
load. To use this function connect ±sense pins directly to
the load as shown in Fig. 6. To use a converter without
remote sense function, connect the ±sense pins to output
pins respectively. This function is available just on single
output models.
